Need help understanding the SAS macro facility? You will find all the answers that you need in this easy-to-follow book! Michele Burlew puts her decades of macro programming experience to work for you as she guides you through the basics, as well as the more complex features of the SAS macro facility, in SAS Macro Programming Made Easy, Second Edition. Updated extensively for SAS 9, this book includes plenty of examples and step-by-step instructions. You will learn the elements of the macro facility (macro variables, macro programs, macro language), how to write a macro program, macro programming techniques, tips on using the macro facility, how the macro facility fits into SAS, and about the interfaces between the macro facility and other components of SAS. New topics for the second edition include using SAS 9 macro and SAS language features, debugging macro programs, adding error checking to macro programs, and building a library of utility macro programs. Beginning macro programmers will learn to write SAS macro programs quickly and efficiently. More experienced macro programmers will find this book useful to refresh their conceptual knowledge and expand on their macro programming skills. It is also important to note that the macro facility is a highly popular part of SAS and found in the job requirements for many SAS programming jobs. In addition, macro facility concepts are tested on the SAS Advanced Programming Exam. The book assumes some SAS programming experience, including knowledge of how to write a DATA step and how to use SAS procedures.
